Apatros was located within the borders of the Galactic Republic. At some point, large quantities of cortosis were discovered underneath the planet's surface, prompting the Outer Rim Oreworks Company to take over Apatros. Outer Rim Oreworks established a colony on the desolate planet and began mining for cortosis, which it sold to the Republic.[1]

Apatros had only one colony on the entire planet, also called Apatros. The Apatros colony was primarily used as the home of the cortosis miners and only had two buildings of note: a cantina owned by the Neimoidian Groshik, which was the main retreat of off-duty miners and visiting Republic crews, and a market, once a barracks, which sold basic items at high prices. The colony and mines were connected by a shuttle for transport back and forth. The cortosis mines were maintained by the Outer Rim Oreworks Company, but the death toll for miners was high and their equipment outdated and substandard.[1]

Apatros was mostly inhabited by miners working in the cortosis mines, the majority of which were Humans. However, other species lived on the planet, including a Neimoidian named Groshik who owned a cantina in the Apatros colony. The most famous of Apatros' inhabitants was Dessel, who worked in the cortosis mines for a decade and later became a Dark Lord of the Sith after leaving Apatros.[1]
